AMiHo Renesas / Semtech Based Wireless Module Dev Kit for Smart Energy Networks
- click to enlarge
The AM070 Renesas / Semtech based AMiHo Wireless Meter-Bus / 868 MHz modem is the first of a family of narrow-band multi-channel 868MHz modems. It is designed specifically for Wireless Meter-Bus, but is also suitable for other ISM-band applications.
It is a 20mW transmission power output, low-power, embedded modem with built-in Microcontroller using a Renesas R8C MCU and Semtech SX1231 transceiver. The module uses an AT command interface and supports very
low current standby for battery powered applications, and is suitable for direct connection to a Lithium Thionyle Chloride cell, removing the need for external voltage regulators. There are substantial memory and peripheral resources available for users to add their own application code to the module.
It is supplied with an EN13757-compliant Wireless Meter-Bus software
stack, but is also suitable for other 868MHz ISM-band communications standards including KNX and other wireless control applications. The AM070 is also available as a hardware reference design and software stack for integration in a user’s own design.
AM070 Wireless Meter-Bus Module
- Wireless Modem: Use in stand-alone modem mode, or embed user application on-board.
- RF Operation: Suitable for narrow-band and wideband operation throughout 868MHz ISM band.
- RF Performance: Semtech SX1231 gives class leading link budget of up to 127 dB at 4800 baud.
- Hardware: 16 bit processor with built-in data flash and built-in 32kHz RTC.
- Low Power Operation: Low operating and standby current. Suitable for direct connection to a Lithium Thionyle Chloride cell, combined with the ability to run application code giving the lowest system consumption and longest battery life.
- Software: Full low level platform drivers and EN13757-4:2005 Wireless M-Bus RF stack level drivers provided, including AES128 encryption and decryption - Supports Wireless Meter-Bus S, R and T modes.
- Compliance: The design complies with European Union radio standards (EN301489-1, EN301489-3).
The Evaluation Kit for the AM070 Wireless Meter-Bus modem is a complete evaluation and development system for the AM070 Renesas / Semtech based AMiHo Wireless M-Bus / 868 MHz narrowband modem. It provides a hardware
environment to test the AM070 radio transceiver and the EN13757:4 Wireless Meter-Bus software stack.
It consists of a USB-attached or battery powered master node that may be connected to a PC, a USB or battery-operated slave node (with USB and CMOS-level RS232 communications), 2 x AM070 modules, antennas, batteries
and PC software to allow users to test the functionality of the modems.
EVK070 Wireless Meter-Bus Evaluation Kit
- The EVK070 is supplied with two USB compatible modules for the evaluation and testing of applications running on the AM070 Wireless M-Bus narrow band 868MHz modem.
- All of the AM070 connector pins are brought to 0.1” pitch connector pads, enabling the connection of switches, potentiometers and other I/O.
- Additional application LEDs are provided for signal strength monitoring and can also be used for a user’s own application.
- Power for the modules can be provided by the USB connection or from an on-board battery pack.
- All additional hardware can be disabled to allow true power consumption measurements.
